My FFL uses USPS and I don’t think he has had any problems with loss but a couple of damage claims. I think he has had loss problems with other shippers.
Yup, I just lost one to FedEx ground. Driver filed a false report of delivery and signed the business name. Thing is, the receiving FFL has full camera coverage of the front of his property, and NO FedEx came that day. Because I am "not a licensee", I will have to eat the gun. CLaim denied.
